Hi,
Ich habe vor kurzem angefangen in Java mit Swing zu arbeiten. Mit Kommandozeilen habe ich schon etwas länger gearbeitet.
jetzt möchte ich einen Taschenrechner programmieren. Vorbild ist der MS-Rechner.
So ich kopiere jetzt ma meinen code rein, dann zum Problem.
Also ich habe noch net alle Buttons verseht, ich möchte es so machen, man kann die zahlen eintippen oder die Buttons betätigen.
Wenn ich dann auf + drücke soll die zuvor eingebene Zahl gespeichert werden und man gibt die nächste ein, wenn man dann = drückt wird es ausgerechnet.
So da habe ich meine Probleme, denn wenn man ja mehrmals + verwendet überschreibt er bei mir den alten wert.= ist noch gar nicht defeniert, da erst das Problem gelöst werden muss.
Oder sollte man vlt. oben eine Formel eingeben und so bald = kommt ausrechnen?
Also:
14+45+3*4*5/5 (Punkt vor strich muss man dann mit if realisieren) und wenn jetzt = gibt er das Ergebniss aus.
Ich bitte um Vorschläge und vlt. auch schon Ansätze.
